T8-G3 Modbus

[Fuchs]

Hi guys,
I have a new T8-G3 and want to connect it to my home assistant via modbus.
The T8-G3 is connected to my home assistant via an isolated USB-RS485 converter.
https://www.waveshare.com/usb-to-rs485-422.htm

I downloaded the https://github.com/nathanmarlor/foxess_modbus integration.
When installing, I chose "USB to RS485 Adapter".
The adapter selected is "Waveshare USB to RS485 (B)".

Home assistant finds the adapter, but unfortunately doesn't get a response from the T8-G3.
I naturally tried swapping A-B of the RS485 first.


1. Question
Is the T8-G3 supported at all?
It is not listed in the documentation


2. Question
Does anyone know the pinning of the T8-G3 connector?
The documentation shows an 8-pin connector, but I found a 16-pin connector (a meter from the installer is connected to pins 3+4).

I used pins 1+2


3. Question
Can the ID247 fit?
The inverter does not have a menu item where I can read this.

Thanks and best regards from Germany,
Marc

Sorry to say that the https://github.com/nathanmarlor/foxess_modbus integration doesn’t work with T series inverters, some work has been done in this integration https://github.com/assembly12/Foxess-T ... -Assistant

You can also get on-line via the cloud fairly quickly using this integration which use the OpenAPI to get data (albeit based on the 5 minute samples the datalogger sends) https://github.com/macxq/foxess-ha

Thanks for fast feedback!

Have you received the connector assembly for the new connector in the meantime? Foxess apparently doesn't give them out when asked by the installer, that's kind of confusing, what could be the reason for that.

Thanks
